The next time a shooter comes up to you at the range, and says: “My rifle shoots one-third MOA all day long”, challenge him to put a first-round hit on a 1/2 MOA plate at 1000 yards. There’s a difference between shooting small groups at close range (Precision) and “on-target” Accuracy at long range.
Article by Applied Ballistics, LLC
Just how much better is a 0.5 MOA rifle vs. a 1 MOA rifle? Is it worth chasing quarter-MOA if you have half-MOA rifle? This is an important question. If you look across Facebook you will find scores of shooters posting 1/3-MOA or 1/4-MOA shot groups [usually at 100 yards]. Some of those guys are spending countless hours trying to chase that golden quarter-MOA group.
Don’t take this statement the wrong way, having a good, consistent rifle is a key to success. But accuracy is extremely important to long range shooting. Having a precision (0.5 MOA) rifle, but not having put the time in to practice accuracy (hitting a 0.5 MOA plate first shot at 1000 yards) is counter-productive. [Editor: By this, we mean that you can have a rifle capable of shooting small groups at 100 yards, but you won’t see that gun’s full potential unless you can practice and perfect the skills of long-range shooting. Successful long range shooting demands more than precision alone.]
What if, your goal was to produce 5-shot, sub-half-MOA groups at 1000 yards instead of 100 yards? Think about how much more you would be including in the learning process, especially that all-important factor: managing the wind! Here is a good article that talks about Precision vs. Accuracy: Hitting Targets at Long Range.
This is not intended to say that precision is not important; rather it is intended to show that balance is important. You can use WEZ to do your own studies on this very subject, and it might be surprising to the shooter just how much you don’t gain by chasing precision over accuracy. Two books which cover this subject really well are Accuracy and Precision for Long Range Shooting and Modern Advancements in Long Range Shooting Vol 2.
Here’s a stunning combination of Precision (small group) WITH accuracy (centered on target). Yep that’s ten shots at 1000 yards, all in the middle of the target:
Video Demonstrates Amazing 1000-Yard Accuracy AND Precision
Watch the video. You can see the group form up, shot by shot. It’s pretty amazing. Scott’s first shot (at the 45-second mark of the video) was right in the X-Ring, and four of Scott’s first five shots were Xs. That’s drilling them!
Comments
“Accuracy with precision is the route for me. It is not an either/or game. If I have a precision rifle (0.25 MOA or less) and I practice to be accurate, then high scores will be the result — Jim Borden
“I would agree for PRS, hunting, and to a certain extent F-Class. However, for 1000-yard IBS benchrest competition, 0.5 MOA groups in good conditions will almost always loose the relay.” — James B
“Another thought is that [at 1000 yards] a 1 MOA gun with single-digit standard deviations [may] out shoot a 0.5 MOA rifle with standard deviations of 20+ fps.” — Beard Owens
“Both… you need both: Accuracy AND Precision. I competed in varmint matches — we shot small silhouettes at 600 yards. I started with a factory .260 Rem rifle that was 0.8 MOA on a good day. I typically hit 8-9 of 20 targets, but rarely nailed the small chickens — which had a hit zone just 4″ in diameter. I then started using a semi-custom 6mmBR rifle that could reliably deliver 1/4 MOA at 100 yards (honest). My hit count on the silhouettes zoomed to 15-18, and suddenly the chickens were going down. In that game — small targets at 600 yards — there was no substitute for precision.” — Paul McM
The folks at Applied Ballistics have a new toy — a large trailer filled with all the latest and greatest tech gear for testing long-range ballistics. Bryan Litz reported: “The maiden voyage for the AB Mobile Lab in Texas this week was a huge success! We look forward to supporting more long range shooting events.” Mitchell Fitzpatrick was there in the Lone Star state with fellow Applied Ballistics staffer Christopher Palka. The Applied Ballistics team will be trailering the Mobile Lab to Indiana where it will be on hand for the NRA National Championships at Camp Atterbury this month.
Ten rifles, heaps of cables, huge Doppler Radar unit, military-grade Laser RFs on tripods, spare barrels, safety gear — all ready for action in Texas.
About the Applied Ballistics Mobile Lab
Q: What is the basic purpose of the Applied Ballistics Mobile Lab?
Mitchell Fitzpatrick: The Mobile Lab allows us to effectively carry out ballistics testing in the field and at events. It has most of the capabilities of our normal lab, but on wheels.
Q: What hardware and electronics are carried in the Mobile Lab? What are its capabilities?
Bryan Litz: The Mobile Lab will transport most everything that’s in the main lab including the Doppler radar. This rig is new and we haven’t fully outfitted it yet. The load-outs will be somewhat flexible depending on the venue we are supporting.
The three rifles on the left are Barrett MRADS, $6000-$6154 MSRP, before optics.
NOTE to Readers — Check back at the end of the day. We will have more technical information from Bryan Litz and the Applied Ballistics team…
The .375 EnABELR cartridge was developed to offer magazine feeding capabilities with the highest-BC solid bullets available. Applied Ballistics observes: “The best magazine is one that retains the cartridge shoulder and doesn’t allow the tip of the bullet to impact the front of the magazine during recoil.” Cadex Defense has designed magazines that fit Cadex’s bottom metal and chassis for the EnABELR line of cartridges which allows for maximum magazine fed performance. These mags are beautifully made, but they will be very EXPENSIVE. Expect to pay about $275 per magazine — what the Cadex 375/408 CheyTac magazine currently costs (Product Code: MAG4300, USD $273.95).
Q: Is this different than Cadex’s regular CheyTac magazine?
A: Mitchell Fitzpatrick of Applied Ballistics Weapons Division replied: “Yes, the ribs that retain the shoulder are moved back to hold the case back and prevent the bullet tip from hitting the front of the magazine. We had been playing with inserts welded into place, which worked great, but dedicated mags directly from Cadex was the ultimate goal.”
Here is Mitchell Fitzpatrick, shooting the .375 EnABELR in an ELR Competition.
“CADEX and Applied Ballistics. Two companies taking ELR seriously and trying to get that last 1-2% of performance out of the system. Keep up the good work!” — Mark N.
The .375 EnABELR Cartridge — Big and Fast
The .375 EnABELR cartridge is slightly shorter than a .375 CheyTac so it allows the round to mag-feed. Applied Ballistics is currently using brass made by Peterson. The .375 EnABELR has achieved impressive velocities — 2990 FPS — with prototype Berger 379-grain solid bullets fired from a 1:7″-twist 30″ barrel. Applied Ballistics may also test 1:8″-twist and 1:9″-twist barrels. READ Bullet Testing Report.
The .375 EnABELR cartridge was designed to offer .375 CheyTac performance in a slightly shorter package: “The problem with the .375 CheyTac is that, when loaded with the highest performance .375 caliber bullets (379-407 gr Berger Solids, and the 400-425 grain Cutting Edge Lazers) the round is not magazine feed-able in any action that’s sized for CheyTac cartridges.
“Knowing the .375 CheyTac produced substantial performance, and that it was just too long for magazine feeding, made it easy to converge on a design for the .375 EnABELR. We just had to make the case short enough to achieve magazine length with the desired bullets, while adding a little more diameter to keep the case capacity similar to the .375 CheyTac. The resulting basic shape is quite similar in proportions to the successful .338 Norma Magnum Cartridge which, interestingly, was selected as the cartridge for General Dynamics Lightweight Medium Machine Gun (LWMMG).”
Emil Praslick III is widely recognized as one of the greatest wind wizards on the planet — a master at identifying wind value and direction, and predicting wind cycles. As coach of the USAMU and top civilian teams, Emil has helped win many high-level championships. In the three videos we feature today, Emil, who works with Capstone Precision Group (Berger, Lapua, SK, Vihtavuori) and Team Applied Ballistics, explains how to determine wind direction and velocity using a variety of indicators. Praslick, now retired from the U.S. Army, was an 18-time National and 2-time World Champion coach with the USAMU.
Video ONE: Wind Theory Basics — Understanding “Wind Values”
In this video from UltimateReloader.com, Emil explains the basics of modern wind theory. To properly understand the effect of the wind you need to know both the velocity of the wind and its angle. The combination of those variables translates to the wind value. Emil also explains that the wind value may not be constant — it can cycle both in speed and velocity. Emil also explains some of the environmental conditions such as mirage that can reveal wind conditions.
Video TWO: Determining the Direction of the Wind
Key Point in Video — Find the Boil
Emil explains how to determine wind direction using optic. The method is to use spotting scope, riflescope, or binoculars to look for the “Boil” — the condition in mirage when the light waves rising straight up. The wind will generate that straight-up, vertical boil in your optics when it is blowing directly at you, or directly from your rear. To identify this, traverse your scope or optics until you see the boil running straight up. When you see that vertical boil, the direction your optic is pointing is aligned with the wind flow (either blowing towards you or from directly behind you).
Video THREE: The No Wind Zero Setting
In this second video, Emil defines the “No-Wind Zero”, and explains why competitive shooters must understand the no-wind zero and have their sights or optics set for a no-wind zero starting point before heading to a match. In order to hit your target, after determining wind speed and direction, says Emil, “you have to have your scope setting dialed to ‘no wind zero’ first.”
Coach of Champions — Emil Praslick III
SFC Emil Praslick III, (U.S. Army, retired) works with Berger Bullets and Applied Ballistics. Emil served as the Head Coach of the U.S. National Long Range Rifle Team and Head Coach of the USAMU for several years. Teams coached by Emil have won 33 Inter-Service Rifle Championships. On top of that, teams he coached set 18 National records and 2 World Records. Overall, in the role of coach, Praslick can be credited with the most team wins of any coach in U.S. Military history.
Hail the King — Paul Phillips wears crown as the new 2019 King of Two Miles.
Paul Phillips, Captain of Team Global Precision Group (GPG), is the 2019 King of 2 Miles. Hail the new King! Paul won the event with a score of 48350, beating runner-up Robert Brantley who scored 46306. Fellow GPG shooter and 2017 K02M winner Derek Rodgers finished third with 38747. Phillips secured his K02M crown with good shooting in Raton, NM on both Day 1 and Day 2. On the final day, Paul had two hits at 2728 yards and one at 3166 yards. No competitor scored more than one hit at 3166 yards (1.799 miles), and no competitor scored even a single hit at the farthest target, placed at 3525 yards (2.0028 miles). So the actual 2-Mile target was never hit during the event.
Here are the target locations and yardages for K02M Day 2 Finals.
Team GPG members Derek Rodgers, Paul Phillips (center), and Mark Lonsdale with KO2M-winning rifle, K02M Trophy, $5000 Winner’s Prize from McMillan, and Nightforce Certificate.
Team Global Precision Dominates with Three of Top Four Places
Team Global Precision Group was top team overall with Paul Phillips in First Place, Derek Rodgers in Third, and Mark Lonsdale in Fourth. Team GPG, in its first world-level match together, dominated the field of 80 of the best ELR shooters in the world. First, Third, and Fourth — that’s mighty impressive gentlemen!

Paul Phillips, who recently competed in the European K02M match in France, gave credit to his sponsors and team-mates: “Team GPG is honored to be … King of 2 Mile Champions. I’ve always wondered what it would feel like to be carried around on the King chair. I am humbled to be added to the list of great shooters that have been crowned before me.”
Paul added: “Big shout-out to all our sponsors, the match organizers, Eduardo, FCSA, and the volunteers who work so hard to make these ELR matches a major success. We’ll definitely be back in 2020!”
“Paul Phillips your win in this match is yet another example of the value of hard work paying off. I can honestly say that I don’t know anyone who works harder at ELR competition and promotion than you do. You deserve this win!” — Bryan Litz, Applied Ballistics
Equipment List for .416 Barrett 2019 KO2M-Winning Rifle
Paul’s massive KO2M rig features a BAT EX .50-Cal action with a 38″ Bartlein 1:9″-twist 5R barrel chambered for the standard .416 Barrett cartridge. The stock is a McMillan Beast One model. To tame recoil, Paul runs a T5 Terminator muzzle brake. The scope is a Nightforce 7-35x56mm ATACR F1 with MOAR Reticle. Up front is a Phoenix Precision Bipod, with an Edgewood Mini-Gator Bag in the rear. Paul is running a Bix’N Andy Comp Trigger with a 4-ounce, single-stage pull.
The complete rifle weighs 40 pounds. Bartlein did the .416 Barrett chambering using a Dave Manson reamer. Alex Sitman bedded the action in the McMillan stock as he did for the other GPG rifles. In fact, all three Team GPG rifles are essentially identical.
Load Details: Standard .416 Barrett cartridge, running .416 Caliber 550gr solid Cutting Edge Bullets at 3000 fps. The powder is Vihtavuori 20N29 ignited by RWS .50 Caliber primers. The cartridge brass is Barrett brand, produced by RUAG.
Support Gear: Ballistics are calculated with Applied Ballistics Software using velocity data from a LabRadar chronograph. Swarovski provided Team GPG with two big BTX 95 binocular spotting scopes. Phillips says “these BTX 95s really help us follow trace, spot impacts, and get on target quickly.”
Here are Team Applied Ballistics competitors at the 2019 KO2M event in Raton, NM. Applied Ballistics’ Mitchell Fitzpatrick posted: “[There were] some unique challenges this year, but I managed to finish in 5th place running a sub-25 pound rifle. That’s the result of a lot of our ESSO research.”
$5000 KO2M Winner’s Prize from McMillan Fiberglass Stocks
McMillan Fiberglass Stocks is a strong supporter of the shooting sports. Here Kelly McMillan presents Paul Phillips with a $5,000 check from McMillan Fiberglass Stocks for winning the 2019 King of 2 Mile while shooting a McMillan stock. Teammates Derek Rodgers and Mark Lonsdale also used McMillan stocks in the 2019 K02M Finals. Along with the McMillan check, Paul Phillips received $5000 from Nightforce Optics, and $1200 from Cutting Edge Bullets. Paul told us he will divide all the winnings with his team-mates because: “I won with my team — we won together.”

Vu Pham takes a shot at the Snake River Sportsman Range in Oregon. Click image for full-screen version.
Vu Pham recently attended a great practical/tactical match, the Gem State Stand Off. This NRL-sanctioned match drew 113 shooters, including many of the best PRS/NRL competitors in the country. Vu says this was a great event: “The 220-round, 22-stage course of fire was fun, yet challenging. Every stage had a two-minute par time requiring 10 rounds fired at multiple targets. 113 competitors fired about 24,000 rounds without a single target failure.”

“With technological advances in equipment, training, and ballistics, plus increased opportunities for competitors to fine-tune their skills, Practical Precision Rifle competition has become a perfectionist sport. The constant evolution of this discipline never ceases to amaze me. With competitors and manufacturers constantly pushing to gain an edge… there is no shortage of innovation.” — Vu Pham
Gem State Stand Off — After Action Report
Report by Vu Pham, NorCal Practical Precision Rifle Club
I was fortunate enough to snag a last-minute slot for the 2019 Gem State Stand Off hosted by the Precision Rifle Shooters of Idaho Club (PRSID). This is one of 17 National Rifle League events where competitors will battle for points hoping to secure a slot for the 2019 NRL Championship. The Snake River Sportsman Range is a beautiful venue in Vale, Oregon, near the Idaho border.
The digital display carries ballistics info and elevation/windage tables from Vu Pham’s Kestrel. He says the unit really helps his performance.

Hardware Report — Top PRS/NRL Gear for 2019
Modern Precision Rifle Comp Gear — Stocks and Chassis Systems
The traditional rifle stock we know has now moved to more modular and customizable designs. One product that caught my eye is the new XLR Industries Envy JV Heavy Fill Chassis system. After seeing a lot of competitors use them with good results, I think I will be giving one a try soon. Not being able to borrow a piece of gear because the entire squad is running ARCA can be a drag. Picatinny forearm rails have gone the way of the dinosaur with ARCA Swiss becoming the standard for attaching accessories.
Those like myself who may not want to give up their traditional-style stocks do have the option of modifying their existing stock with a universal ARCA rail from Henderson Precision. That company makes a variety of rails that fit a number of stock platforms.
Rifle Support Options — Bags and Tripods
Tripods are also used a lot as front and rear support by the majority of the field as well. Support bags now come in every shape, size, weight, and material imaginable. Even the fundamentals of driving your rifle is being challenged by the evolution of “free recoil”. Instead of counting the number of hits for the day, the top echelon shooters count the number of shots they dropped.
Calibers of Choice — Small is Big — the 6mms Dominate
6mmBR Improved cartridges (6mm Dasher, 6BR Ackley) and mid-sized 6mms (such as 6mm Creedmoor) dominate the field. In addition we are seeing some guys running the 22 BR and 22 BRA, which work surprisingly well. [Editor: Run the ballistics with a .22 Cal 80-grainer and you’ll see why.]
Wind Monitoring and Ballistics
Kestrel Environmental Meters with Applied Ballistics are “must haves”. I have found my Really Right Stuff tripod and Vortex 12×50 Razor binoculars extremely useful for locating targets and going through the target shooting order before it was my turn to shoot. Watching what the wind and competitor’s rounds are doing before you are on the gun is a huge benefit.
Great Match with Great Shooters
Tough Competition with a Field of Ace Practical Marksmen
The field of competitors at this match was stacked. I heard there were 20 competitors in attendance who have won national-level PRS or NRL events. 20 top-echelon competitors mixed in with a solid field of shooters made it a tough for anyone looking to finish at the top.
Have you recently purchased a new scope? Then you should verify the actual click value of the turrets before you use the optic in competition (or on a long-range hunt). While a scope may have listed click values of 1/4-MOA, 1/8-MOA or 0.1 Mils, the reality may be slightly different. Many scopes have actual click values that are slightly higher or lower than the value claimed by the manufacturer. The small variance adds up when you click through a wide range of elevation.
In this video, Bryan Litz of Applied Ballistics shows how to verify your true click values using a “Tall Target Test”. The idea is to start at the bottom end of a vertical line, and then click up 30 MOA or so. Multiply the number of clicked MOA by 1.047 to get the claimed value in inches. For example, at 100 yards, 30 MOA is exactly 31.41 inches. Then measure the difference in your actual point of impact. If, for example, your point of impact is 33 inches, then you are getting more than the stated MOA with each click (assuming the target is positioned at exactly 100 yards).
How to Perform the Tall Target Test
The objective of the tall target test is to insure that your scope is giving you the proper amount of adjustment. For example, when you dial 30 MOA, are you really getting 30 MOA, or are you getting 28.5 or 31.2 MOA? The only way to be sure is to verify, don’t take it for granted! Knowing your scopes true click values insures that you can accurately apply a ballistic solution. In fact, many perceived inaccuracies of long range ballistics solutions are actually caused by the scopes not applying the intended adjustment. In order to verify your scope’s true movement and calculate a correction factor, follow the steps in the Tall Target Worksheet. This worksheet takes you thru the ‘calibration process’ including measuring true range to target and actual POI shift for a given scope adjustment. The goal is to calculate a correction factor that you can apply to a ballistic solution which accounts for the tracking error of your scope. For example, if you find your scope moves 7% more than it should, then you have to apply 7% less than the ballistic solution calls for to hit your target.
NOTE: When doing this test, don’t go for the maximum possible elevation. You don’t want to max out the elevation knob, running it to the top stop. Bryan Litz explains: “It’s good to avoid the extremes of adjustment when doing the tall target test.I don’t know how much different the clicks would be at the edges, but they’re not the same.”
Should You Perform a WIDE Target Test Too?
What about testing your windage clicks the same way, with a WIDE target test? Bryan Litz says that’s not really necessary: “The wide target test isn’t as important for a couple reasons. First, you typically don’t dial nearly as much wind as you do elevation. Second, your dialed windage is a guess to begin with; a moving average that’s different for every shot. Whereas you stand to gain a lot by nailing vertical down to the click, the same is not true of windage. If there’s a 5% error in your scope’s windage tracking, you’d never know it.”
Verifying Scope Level With Tall Target Test
Bryan says: “While setting up your Tall Target Test, you should also verify that your scope level is mounted and aligned properly. This is critical to insuring that you’ll have a long range horizontal zero when you dial on a bunch of elevation for long range shots. This is a requirement for all kinds of long range shooting. Without a properly-mounted scope level (verified on a Tall Target), you really can’t guarantee your horizontal zero at long range.”
NOTE: For ‘known-distance’ competition, this is the only mandatory part of the tall target test, since slight variations in elevation click-values are not that important once you’re centered “on target” at a known distance.
